What is the circular enclosure that the magnetic compass is placed in ? stainless steel case aluminium case nickel case iron case None 4. The end of a free hanging magnet which points towards North is called North pole West pole South pole East pole None 5. How will hammering a bar magnet affect Its magnetic strength? Is likely to decrease None of the above Will not change Is likely to increase None 6. Which of the following will help demagnetizing a magnet ? Cooling it Hammering the magnet Putting in contact with iron Putting it in the water None 7. The marked end of a compass needle always points directly to Earth's geographic South Pole Earth's geographic North Pole A magnet's south pole A magnet's north pole None 8. The presence of magnetic field at a point can be detected by ammeter galvanometer strong magnet a compass needle None 9. How is a compass used to find directions? When suspended freely the compass needle aligns itself in the east-west direction which gives us the perpendicular direction to the needle as north and south poles When suspended freely the compass needle aligns itself in the vertically up-down direction which gives us the perpendicular direction to the needle as north and south poles When suspended freely the compass needle aligns itself in the north-south direction which gives us the direction of the north and south poles When suspended freely the compass needle starts rotating in a particular plane and the axis of rotation perpendicular to the plane gives us north and south poles None 10. Complete the following statements with an appropriate word / term to be filled in the blank space(s).A compass needle is a ________ magnet : small big fieldless super None 11. The device used by sailors and navigator to know the direction is called Wind vane Magnetic compass Speedometer Direction finder None 12. A marine compass is used to determine dip at a place determine H determine direction compare magnetic moments None 13. Which types of magnet have two poles close to each other? Electromagnet Cylindrical magnet Horse-shoe magnet Bar magnet None 14. The answer to which of the following options will distinguish between a magnetic material and a non-magnetic material? Can it be given an electric charge? Is it a metal of a non metal? Is it a conductor or an insulator? Does it affect the direction in which a compass needle points? None 15. Which of the following is not attracted by a magnet? nickel steel bronze cobalt None 16. Which effect of force is caused by the magnetic force between a magnet and a magnetic substance? Change of chemical nature. Change of physical state. Change of shape. Change of position. None 17. Which shape of magnet is used in electric bell? Cylindrical magnet Bar magnet Ball-ended magnet Horse-shoe shaped None 18. Magnet was discovered by 19. Magnetic strength of the magnet is Distributed uniformly throughout the magnet Concentrated in the centre of magnet Concentrated at both the poles of the magnet Concentrated at one of the poles of the magnet None 20. What kind of magnet is used in a magnetic compass ? temporary magnet none of the above electromagnet permanent magnet None Time's up Please Share This Share this content Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Leave a Reply Cancel replyCommentEnter your name or username to commentEnter your email address to commentEnter your website URL (optional) Save my name, email, and website in this browser for the next time I comment.
